Nash functions

The term "Nash functions" is not a standard term in mathematics or economics. However, it seems to be related to Nash equilibria, named after John Nash, a mathematician whose work in game theory has foundational implications in various fields such as economics, political science, and biology. **Nash Equilibrium**: A Nash equilibrium is a concept within game theory where no player can benefit from unilaterally changing their strategy if the strategies of the other players remain unchanged.
